17 Installation of the Landscape PURPOSE AND EXPECTED OUTCOMES The purpose of this chapter is to discuss the activities involved in installing a landscape, following the plans produced by landscape designers. The materials used in a landscape may be plant materials or nonplant materials. After studying this chapter, the student should be able to 1. Define hardscaping. 2. Distinguish between formal garden and informal garden. 3. List five common plants in each of the categories of bedding plants, ground covers, ornamental grasses, trees, and shrubs. 4. Discuss how the plants in each of the categories in (3) above are planted. OVERVIEW Plants used in the landscape may be grouped into certain operational categories—trees, shrubs, vines, bedding plants, ground covers, bulbs, corms, tubers, and rhizomes. Plants in each group have common methods of propagation and require similar care. They differ in various characteristics including adult size, shape, color, texture, and growth environment. These categories of plants have certain specific roles in the landscape. When different categories are used simultaneously in the landscape, they have to be properly located to be effective and functional. This chapter is devoted to discussing how these categories of plants are installed and used in creating effective designs in the landscape. The role of the nursery and its operations are also discussed. 509

17.1 LANDSCAPE CONSTRUCTION Once a planting plan has been prepared, the installation of the landscape can begin. Frequently, however, the site cannot be planted without some modification. A landscape usually consists of more than just plants. Most of the static features are best installed before planting. Hardscaping The installation of nonplant elements in the landscape. 17.1.1 HARDSCAPING Hardscaping is a term used for the installation of hard or static features in the landscape. These features range from simple ones such as fences, walls, patios, and walks to major constructions such as fountains and pools (Figure 17–1). These hard features can significantly enhance the landscape and increase functionality and property value. Walks may be constructed out of concrete, stone, brick, or some other similar material. Concrete is easy to install and inexpensive; however, it has low aesthetic value and creates little interest in the landscape. Bricks themselves are expensive, as is their installation; they are used (a) (b) (c) FIGURE 17–1 Examples of hardscaping materials include (a) brick, (b) wrought iron, and (c) stones.

About Books
The successful systems based formula for teaching financial accounting that gained such academic acclaim in its first and second editions, is back! Financial Accounting remains the student s favourite! The third edition is more streamlined, more user friendly and even more accessible. An in-depth, worked example from an actual partnership, brings alive for students the accounting issues involved in partnerships, a required topic of accreditation. Financial Accounting is based on a threefold approach: an organizational flow-model is used to locate financial accounting in its organizational context; this model is then used to derive a systematic logical approach to financial accounting and the construction of the financial statements; and the text attempts to forge a firm link between the traditional diet of introductory financial accounting and the wider issues of accounting theory. Financial Accounting is the ideal text for undergraduate Accounting students.
